MIROVA (Middle Infrared Observation of Volcanic Activity) is an automatic volcano hot spot detection system, based on the analysis MODIS data (Moderate Resolution Imaging Spectroradiometer). The system able to detect, locate and quantify thermal anomalies in near real-time, by providing, a dedicated website (www.mirovaweb.it), infrared images flux time-series over 200 volcanoes worldwide. Thanks its simple interface intuitive representation data, currently used several observatories for...
Abstract. Lava flow simulations help to better understand volcanic hazards and may assist emergency preparedness at active volcanoes. We demonstrate that Fogo Volcano, Cabo Verde, such can explain the 2014–2015 lava crisis therefore provide a valuable base prepare for next inevitable eruption. conducted topographic mapping in field satellite-based remote sensing analysis. produced first model of from combined terrestrial laser scanner (TLS) photogrammetric data. This high-resolution...
Deep magma accumulation near the crust‐mantle boundary (21 km depth) at Krafla volcanic system is suggested from InSAR observations. A best fit model, derived four interferograms covering 1993–1999, comprises an opening dike, representing plate spreading and post‐rifting deformation, two Mogi sources. source deflating a rate of ∼0.3 × 10 6 m 3 /yr coincides with shallow chamber while deeper inflating source, further north, 21 depth, inflates ∼26 /yr. The or as identified by seismic studies...
Abstract Volcano observatories (VOs) around the world are required to maintain surveillance of their volcanoes and inform civil protection aviation authorities about impending eruptions. They often work through consolidated procedures respond volcanic crises in a timely manner provide service community aimed at reducing potential impact an eruption. Within International Airways Watch (IAVW) framework Civil Aviation Organisation (ICAO), designated State Observatories (SVOs) asked operate...
Abstract We conducted gravity surveys of the summit area Kīlauea Volcano, Hawaiʻi, in November 2018 and March 2019, with goal determining whether there was any mass change at depth following volcano's May–August caldera collapse. Surface deformation between two minimal, but we measured a increase (maximum 44 μGal) centered on that can be modeled as accumulation region ~1 km beneath surface. interpret this to mostly magma void space created during Caldera uplift evident by April indicating...
The stratovolcanoes of Mt. Scenery at Saba and Quill St. Eustatius in the Caribbean Netherlands, with a total population about 5200 people, are part active volcanic arc Lesser Antilles but lacked multiparameter volcano earthquake monitoring system until beginning 2018. permanent seismic network on islands has been built up since 2006 was expanded 2018 one Global Navigation Satellite System (GNSS) sensor each temperature logger Saba. We provide technical details all equipment installation...
Abstract Microgravity time series at active volcanoes can provide an indication of mass change related to subsurface magmatic processes, but uncertainty is often introduced by hydrologic variations and other noise sources that cannot easily be isolated. We empirically assessed seasonality conducting four surveys over the course May–October 2017 Yellowstone caldera, Wyoming. experiences frequent changes in rates styles seismicity surface deformation, mechanisms these are poorly understood....
Abstract. Lava flow simulations help to better understand volcanic hazards and may assist emergency preparedness at active volcanoes. We show that Fogo Volcano, Cape Verde, such can explain the 2014–2015 lava crisis therefore provide a valuable base prepare for inevitable next eruption. In rapid disaster response effort, we conducted topographic mapping in field satellite based remote sensing analysis. produced first model of flows from combined Terrestrial Laser Scanner (TLS)...
Abstract Results from nine microgravity campaigns Kı̄lauea, Hawaiʻi, spanning most of the volcano's 2008–2018 summit eruption, indicate persistent mass accumulation at shallow levels. A weighted least squares approach is used to recover results a network benchmarks around Kı̄lauea's summit, eliminate instrumental drift, and restore suspected data tares. total 1.9 × 10 11 kg was determined these have accumulated below Kı̄lauea Caldera during 2009–2015 an estimated depth 1.3 km sea level. Only...
ABSTRACT The continuous recordings of broadband seismometers on Saba and St. Eustatius in the Lesser Antilles provide a unique long data set to measure temporal seismic velocity variations (dv/v) at two active but quiescent volcanoes (Mt. Scenery Quill). We compare results from single-station cross-component (SC) correlations with cross-station (CC) achieve best similarities within frequency band 1.3–2.1 Hz, average 0.82 for 0.36 Eustatius, justifying use SC as proxy CC these frequencies....
ABSTRACT The seismic network NA (Caribbean Netherlands Seismic Network) in the Caribbean is deployed by Royal Meteorological Institute (KNMI) to monitor local seismicity around Saba, St. Eustatius, and Maarten, contribute data regional earthquake tsunami warning monitoring systems. currently comprises 11 broadband seismometers that record processed real time at KNMI, using SeisComP a coincidence trigger. Between January 2017 April 2022, we detected located 241 earthquakes within 150 km...
Stakeholders in disaster risk management are faced with the challenge to adapt their reduction policies and emergency plans cascading compounding events, but often lack tools account for cross-sectoral impacts dynamic nature of risks involved. The EU Horizon Europe PARATUS project, which started October 2022 will run 2026, aims fill this gap by developing an open-source online platform assessment that allows analyze evaluate multi-hazard impact chains, measures, response scenarios light...
